Lawrence firefighters were dispatched to the rear of 75 Manchester St for a reported explosion/gas leak. Upon arrival of the first due companies, a gas line was struck by a construction crew and was actively leaking. Due to the size of the building and the gas readings in the area, the deputy chief asked for a working fire assignment to the scene. This brought mutual aid into the city to cover.

Supply lines were laid and the master streams were staged ready to go. All of the utilities arrived on scene and secured the power and gas. Crews remained on scene air monitoring.
